Sources: National Illicit Crop Monitoring System supported by UNODC. Notes: Owing to the introduction of an adjustment factor for small fields, estimates since 2010 are not directly comparable with those of previous years. The ranges reflect the uncertainty associated with the estimates. For Bolivia (Plurinational State of) and Peru, the ranges are based on confidence intervals, and the best estimate is the midpoint between the upper and lower bounds of the range. In the case of Colombia, the range is estimated on the basis of the area under coca cultivation in the two previous years. The methodology used to calculate uncertainty ranges for production estimates is still under development, and figures may be revised when more information becomes available.

Sources: For Bolivia (Plurinational State of): Government calculations based on coca leaf yield surveys by UNODC (Yungas of La Paz) and United States DEA scientific studies (Chapare). For Colombia: national illicit crop monitoring system supported by UNODC and DEA scientific studies. Due to the introduction of an adjustment factor for small fields, estimates since 2010 are not directly comparable with those of previous years. For Peru: Government calculations, based on a coca leaf to cocaine conversion ratio from DEA scientific studies. Notes: Owing to the ongoing review of conversion factors, no point estimate of the level of cocaine production could be provided since 2009. Because of uncertainty about the level of total potential cocaine manufacture and about the comparability of the estimates of the various countries, the figures were estimated as ranges (842-1,111 tons in 2009, 788-1,060 tons in 2010, 776-1,051 tons in 2011 and 714-973 tons in 2012). Detailed information on the ongoing revision of conversion ratios and cocaine laboratory efficiency is available in the World Drug Report 2010 (p. 249). Figures in italics are being reviewed. Information on estimation methodologies and definitions can be found in the section on methodology in the online version of this report.
